安装方式 | Installation:
1、确认散热器表面清洁、平整。
2、模块的金属底板表面涂敷导热硅脂,将模块紧紧地压到散热 器上,并确认有良好的接触,然后用螺钉将模块紧定到散热 器上。
3、将导线用螺钉压紧。


1. When mounting the modules side by side, provide a space equivalent to the width of a single module between two adjacent modules. Otherwise , reduce the load current flow to 1/2 to 1/3 of the rated current.
2. When mounting modules on the heat sink surface , first apply a heat conductive grease to the metal back surface of the module. Press the module firmly onto the heat sink to ensure a good seal. Screw the module down to the heat sink .
3. Next , wire the screw terminals and securely tighten the screws.

注意事项 | Precautions:
1、如果模块连接的负载会产生高浪涌电流,一定要注意模块是否能承受该浪涌电流值。
2、本说明书所列的模块浪涌电流值,是指非重复性浪涌电流峰值。一般情况,将此非重复性浪涌电流峰值的一半作为标准值,如 果流过模块的浪涌电流超过此值,必须在输出端串入一只快速熔断器,且快速熔断器I2t值必须小于该产品的最大I2t值,以保护模块免于损坏。
3、由于电机负载会产生高反中电压,所以应注意模块能否承受该瞬态电压值。
4、本说明书所列的模块瞬态电压,是指非重复性阻断电压峰值。如果加在模块输出端的瞬态电压超过此值,必须在模块的输出端 并联一只压敏电阻,以保护模块免于损坏,推荐压敏电阻的保护电压值为750V。
5、模块使用时用户给定的最小正反转切换时间必须符合本说明书的要求。
6、模块选型时,请特别注意负载的工作电流及环境温度,满负载工作时需安装足够的散热器或采取其他有效的散热措施,当环境温度较高时,请参照"最大负载电流与环境温度曲线"进行降额使用。
7、输出接线柱与负载连接松弛时,通电时的发热会导致产品烧毁。以下为产品接线时螺钉的推荐安装:输出螺钉安装,力矩为(0.98- 1.37)N.m,输入螺钉安装,力矩为(0.58 - 0.98)N.m。过大的安装力矩会损坏模块内部元件。
8、推荐使用本公司相配套的散热器,当用户需使用自制散热器时,必须确保模块散热基板温度在最严酷的使用条件下不超过85°C


1. Before connect a load that generates a high surge current ,such as a lamp load to the module, make sure that the module can withstand the surge current of the load.
2. The product data sheet shows the non-repetitive peak value of the surge current that flows through the module. Normally, use 1/2 of the non-repetitive peak surge current as the standard value. If a surge current exceeding that value is expected, connect a quick-acting fuse to protect the module. At the same time, I2t value of the quick-acting fuse must be smaller than the module value.
3. In practice, if the transient voltage may be larger than 800V,a 750V varistor should be mounted to the load terminals.
4. When the module is put into use,the minimum switching time by user offer must meet this specification.
5. Please pay more attention to actual load current and ambient temperature for module selection. When the moudle is used for full load operation, we'd better install an adequate heatsink or take other effective cooling measures. When the ambient temperature is high, please refer to the follow-up characteristic curves for derating.
6. Tighten the module terminal screw properly. If the screws are 
not tight, the module will be damaged by heat which is generated when module turn on. Perform wiring using the tightening torque shown in the following table.
7. It's recommended to use the matched heatsink,When a user need use home-made heatsink, it's needed to ensure that the module base temperature does not exceed 85°C
